Correct, SCSI_QLOGIC_1280_1040 should depend on SCSI_QLOGIC_1280.

The patch below does this.

Additionally, it prevents the case that both drivers are built
statically and both support the 1020/1040.

      [PATCH] sym53c500_cs driver update · 2b754ab0
      Bob Tracy authored 
      The attached minor patch to linux/drivers/scsi/pcmcia/sym53c500_cs.c
allows interrupt sharing, which is evidently a "must have" feature for
at least G4 PowerBooks (ppc architecture).  The other user of the New
Media Bus Toaster reports that his powerbook consistently assigns the
yenta CardBus controller IRQ to whatever card he inserts.

      [PATCH] sg: Fix oops of sg_cmd_done and sg_release race · fad44d87
      Brian King authored 
      The following patch fixes a race condition in sg of sg_cmd_done racing
with sg_release. I've seen this bug hit several times on test machines
and the following patch fixes it. The race is that if srp->done is set
and the waiting thread gets a spurious wakeup immediately afterwards,
then the waiting thread can end up executing and completing, then getting
closed, freeing sfp before the wake_up_interruptible is called, which
then will result in an oops. The oops is fixed by locking around the
setting srp->done to 1 and the wake_up, and also locking around the
checking of srp->done, which guarantees that the wake_up_interruptible
will always occur before the sleeping thread gets a chance to run.

The problem with using shost_for_each_device wrt to the above oops is
that scsi_forget_host sets the state to SDEV_CANCEL, so that when
scsi_host_cancel iterates over the devices using shost_for_each_device
it cannot get a handle to the sdev (scsi_device_get fails becuase the
state is set to SDEV_CANCEL). And, __scsi_iterate_devices does not clear
the next pointer if this happens, so I think this is needed to fix just
the refcount bug in shost_for_each_device.
